    Eral hard coal-fired power plants in Poland. The hazard of hard coal dust in mining has been well known for years. In the power plants, the hard coal is transported to the furnaces on long conveyor belts (Fig-ures 2 and 3). The coal is largely so coarse-grained that there is no immediate risk of dust explosion. However, unavoidable abrasion.
